The compiler has a phase ordering problem.  Escape analysis runs
before wrapper generation.  When a generated wrapper calls a method
defined in a different package, if that call is inlined, there will be
no escape information for the variables defined in the inlined call.
Those variables will be placed on the stack, which fails if they
actually do escape.

There are probably various complex ways to fix this.  This is a simple
way to avoid it: when a generated wrapper calls a method defined in a
different package, treat all local variables as escaping.

Fixes #9537.

The build was broken on Plan 9 after the
CL 2994, because of the use of getfields
in src/liblink/go.c.

This happened when building 8l, because
getfield was part of lib9 and tokenize
was part of the Plan 9 libc. However,
both getfields and tokenize depend on
utfrune, causing an incompatibility.

This change enables the build of tokenize
as part of lib9, so it doesn't use
tokenize from the Plan 9 libc anymore.

According to RFC5280 the authority key identifier extension MUST included in all
CRLs issued. This patch includes the authority key identifier extension when the
Subject Key Identifier is present in the signing certificate.

RFC5280 states:

"The authority key identifier extension provides a means of identifying the
public key corresponding to the private key used to sign a CRL.  The
identification can be based on either the key identifier (the subject key
identifier in the CRL signer's certificate) or the issuer name and serial
number.  This extension is especially useful where an issuer has more than one
signing key, either due to multiple concurrent key pairs or due to changeover."

Conforming CRL issuers MUST use the key identifier method, and MUST include this
extension in all CRLs issued."

Unless the first element is a Universal Naming Convention (UNC)[0]
path, Join shouldn't create a UNC path on Windows.

For example, Join inadvertently creates a UNC path on Windows when
told to join at least three non-empty path elements, where the first
element is `\` or `/`.

This CL prevents creation of a UNC path prefix when the first path
element isn't a UNC path.

Since this introduces some amount of Windows-specific logic, Join is
moved to a per GOOS implementation.

Fixes #9167.

The code in mfinal.go is moved from malloc*.go and mgc*.go
and substantially unchanged.

The code in mbitmap.go is also moved from those files, but
cleaned up so that it can be called from those files (in most cases
the code being moved was not already a standalone function).
I also renamed the constants and wrote comments describing
the format. The result is a significant cleanup and isolation of
the bitmap code, but, roughly speaking, it should be treated
and reviewed as new code.

The other files changed only as much as necessary to support
this code movement.

This CL does NOT change the semantics of the heap or type
bitmaps at all, although there are now some obvious opportunities
to do so in followup CLs.
